MP1653FGTF-Z MPS synchronous buck converter
The MP1653FGTF-Z is a high-efficiency synchronous step-down converter from Monolithic Power Systems (MPS), integrating low RDS(ON) power MOSFETs in a compact 6-pin SOT563 (1.6mm×1.6mm) package for space-constrained power supply designs. It operates over a wide 4.5V to 16V input voltage range, delivers up to 3A continuous output current, and supports an adjustable output voltage from 0.6V to 8V. Featuring constant-on-time (COT) control, it provides fast transient response, simple loop compensation, and tight output regulation with ±1% feedback accuracy at room temperature. The device includes comprehensive protection features such as short-circuit protection (SCP), over-current protection (OCP), thermal shutdown, and input over-voltage protection (OVP), ensuring safe and reliable operation in various fault conditions.
Step-down converter Key Features and Applications
This buck converter achieves high efficiency up to 95% thanks to its 32mΩ/58mΩ low on-resistance internal MOSFETs and synchronous rectification, minimizing power dissipation and extending battery life in portable systems. It switches at a fixed 1.1MHz frequency, balancing efficiency and external component size while reducing EMI. The device offers pre-bias startup, enabling (EN) pin for power sequencing, and hiccup-mode OCP for robust current limiting. With a low 180μA quiescent current and an industrial temperature range of -40°C to 125°C, it is optimized for both consumer and industrial applications requiring high efficiency and compact size.
It is widely used in consumer electronics such as set-top boxes, LCD monitors, and home theater systems, providing efficient point-of-load regulation. It serves portable devices like tablets, notebooks, and power banks, where its small package and high efficiency are critical for battery-powered operation. Additionally, it is applied in industrial control systems, automotive infotainment, and ADAS, delivering reliable step-down conversion for 5V, 3.3V, and 1.8V power rails in compact, high-density designs.
